Answer:
C
10 x (p+2) = 30
10 x 2 = 20 30 - 20 = 10 10 ÷ 10 = 1
P = 1
10 x (1 + 2) = 30
The given equation is:
We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.
From first equation, we can write t =x/5. Using this value in second equation, we get:
Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A
Answer:
(a) 1.4 hours or 1 hour 24 minutes.
(b) 15 miles.
(c) (5/6)t miles.
(d) 70 - (5/6 t miles.
Step-by-step explanation:
(a) speed = distance / time
50 = 70 / t
t = 70/50
t = 7/5
t = 1.4 hours.
(b) 18 minutes = 18/60 = 0.3 hours.
50 = distance / 0.3
distance = 50 * 0.3
= 15 miles.
(c). 50 = d / (t/60)
50 = 60d / t
60d = 50t
d = (5/6) t miles.
(d) Number of miles remaining after t minutes = 70 - (5/6) t miles.
